P0715

TECHNICAL DESCRIPTION
When a malfunction of the input shaft speed sensor is detected, the transaxle control CPU inside the powertrain control module (PCM) outputs a malfunction signal to the engine control CPU in the PCM.

DTC SET CONDITIONS

Check Conditions, Judgment Criteria
Input shaft speed sensor failure signal is input to the engine control CPU from the transaxle control CPU. Both CPUs are in the PCM.

TROUBLESHOOTING HINTS (The most likely causes for this code to be set are:)
- Input shaft speed sensor failed.
- Open or shorted input shaft speed sensor circuit, or loose connector.
- PCM failed.

DIAGNOSIS

Required Special Tools
MB991502: Scan Tool(MUT-II)




STEP 1. Using scan tool MB991502, read the A/T diagnostic trouble code (DTC).

CAUTION: To prevent damage to scan tool MB991502, always turn the ignition switch to the "LOCK"(OFF) position before connecting or disconnecting scan tool MB991502.

1. Connect scan tool MB991502 to the data link connector.
2. Turn the ignition switch to the "ON" position.
3. Check the A/T-DTC.
4. Turn the ignition switch to the "LOCK"(OFF) position.

Q: Is the A/T-DTC is output?

YES: Refer to Automatic Transaxle Diagnosis - Diagnostic Trouble Code Chart.

NO: If DTC P0715 is output again after the MFI-DTC has been erased, replace the PCM. Then check that the DTC P0715 does not reset.
